Civil Reference No. 7 of 2004
The appellant, Executive Director of the NGO Twaweza, was sought by Tanzania Immigration officers who left a message for him to report to their Kurasini offices. On 23 July 2018 he reported and was informed his citizenship was under investigation. He was directed to surrender his passport, which he did on 24 July 2018. Despite written requests, the passport was not returned. On 1 August 2018 he was prevented from boarding a flight to Kenya on an emergency travel document because his citizenship status was 'still under investigation.' Having failed to recover his passport, he sought leave and filed Misc. Civil Cause No. 11 of 2019 in the High Court seeking prerogative orders of certiorari, mandamus and prohibition against the Commissioner General and Commissioner of Citizenship and Passports, and the Attorney General. The High Court (Mlyambina, J.) dismissed the application for lack of merit, holding, among other things, that there was no set time limit for investigations, that the one-year investigation was not unreasonable, and that the application was premature since investigations were ongoing. The appellant appealed to the Court of Appeal on fourteen paraphrased grounds.
(1) Whether the High Court erred in relying on DPP v. Shaban Donasian and Others to conclude there is no reasonableness limit on investigation duration and that the application was premature. (2) Whether the seizure and prolonged retention of the appellant's Tanzanian passport by immigration officers, purportedly for citizenship investigation, was lawful under section 16 of the Immigration Act and section 4(2) of the Tanzania Passports and Travel Documents Act (TPTDA). (3) Whether the roughly one-year retention of the passport without communication was reasonable, and whether it infringed the appellant's constitutional right to freedom of movement under Article 17(1) of the Constitution. (4) Whether the appellant was denied the right to be heard and whether due process/natural justice was observed. (5) Whether the High Court erred in the manner it framed and determined the issues (including alleged misquotation of section 2(2)(a) of the Immigration Act and failure to follow Order XIV rule 5 of the Civil Procedure Code). (6) Whether the appellant was entitled to the prerogative orders of certiorari, mandamus and prohibition sought.
Appellant: Argued that the High Court misconstrued DPP v. Shaban Donasian, a case concerning denial of the right to be heard in criminal revisional proceedings, not a holding that investigations have no time limit; that section 16 of the Immigration Act only permits investigation where there is reasonable cause to believe an offence has been or is about to be committed, and does not authorise seizure of a passport; that section 2(2) of the Immigration Act generally excludes Tanzanian citizens from its application except in narrow circumstances, which the trial judge misquoted by omitting the word 'not'; that the passport was taken without any written notice or charge, contrary to sections 4(2), 11 and 17 of the TPTDA, and that seizure was unnecessary since investigation could proceed without possession of the passport; that the year-long retention, absent explanation, was unreasonable, breached natural justice/right to be heard, and unlawfully curtailed his constitutional right to freedom of movement (Article 17(1)); and that the trial judge wrongly framed issues without party participation, contrary to Order XIV rule 5 CPC, and treated the matter as a criminal investigation rather than judicial review.
Respondents: Contended that immigration officers lawfully exercised powers under section 16 of the Immigration Act and section 4(2) of the TPTDA to seize and retain the passport because they had reasonable cause to investigate the appellant's citizenship, and that the appellant was duly informed orally of the reasons. They argued no statute prescribes a time limit for investigations or a specific seizure procedure, so the actions taken fell within lawful discretion; that the passport remains government property under section 4(1) TPTDA, supporting the authorities' power to retain it; that freedom of movement was not infringed since the appellant could move freely within Tanzania; that the issues framed by the High Court, including duration of investigation, were properly derived from the parties' submissions and pleadings, consistent with practice in application (rather than suit) proceedings; and that the High Court correctly found the application premature because investigations had not concluded.
The Court of Appeal allowed the appeal in part. It held that the High Court misconstrued the ratio of DPP v. Shaban Donasian and Others, which concerned denial of the right to be heard in revisional proceedings and did not establish that investigations have no time limit; this misconstruction led to an erroneous finding that the one-year investigation was not unreasonable and that the application was premature. The Court found that seizure of the appellant's passport was, in principle, lawful under section 4(2) of the TPTDA (which makes the passport government property held by the citizen subject to lawful cause for removal) read with section 16 of the Immigration Act (empowering investigation where there is reasonable cause to suspect contravention), and that the absence of a written notice did not itself vitiate the investigation since the appellant was informed orally of the reason. However, applying reasonableness factors adapted from the US case Telecommunications Research and Action Center v. FCC ('TRAC'), the Court found that the respondents failed to show the year-long delay in concluding investigations and returning the passport was governed by any 'rule of reason'; the delay was unexplained, prejudiced the appellant by curtailing his constitutional right to freedom of movement under Article 17(1), and was therefore unreasonable and unjustified. The Court rejected the claim that the trial judge's misquotation of section 2(2)(a) of the Immigration Act (omitting 'not') caused injustice, since the substantive legal position—permitting investigation of Tanzanian citizens where there is cause under sections 16 and 2(2)(a)—remained correctly applied. It also held that Order XIV rule 5 of the Civil Procedure Code, which concerns issue-framing in suits with party participation, did not strictly apply to this application proceeding, and that the issues framed by the trial judge were properly drawn from the parties' pleadings and submissions, including the agreed issue of investigation duration; hence no denial of the right to participate in issue framing occurred. The Court found the High Court did apply judicial review principles (citing Sanai Murumbe v. Muhere Chacha) rather than purely criminal-investigation reasoning, so that ground failed. Ultimately, applying a proportionality-style test, the Court concluded that while the initial seizure was lawful, its prolonged, unexplained retention became unreasonable and infringed the appellant's rights. The appeal was allowed to that extent: the High Court's decision was quashed; the respondents were ordered to finalize the citizenship investigation within 60 days and thereafter immediately return the passport or facilitate issuance of a new one if the original had expired. No order for prohibition was made, and no order as to costs.
The judgment clarifies that although immigration and passport legislation in Tanzania (sections 16 and 2(2)(a) of the Immigration Act, and sections 4(2) and 11 of the TPTDA) permits investigation of, and temporary retention of a passport from, a Tanzanian citizen where there is lawful cause to question citizenship, such administrative action must be exercised reasonably and within a 'rule of reason' as to time. The decision imports and adopts, as persuasive guidance, the US TRAC factors for assessing 'unreasonable delay' by administrative agencies in the Tanzanian judicial review context, marking a notable methodological development for evaluating agency inaction/delay. It also reaffirms that prolonged, unexplained administrative delay affecting fundamental rights (such as freedom of movement under Article 17(1) of the Constitution) can render an otherwise lawful administrative action unreasonable and subject to correction via judicial review remedies, even absent a statutory deadline. Additionally, the case underscores that misapplication or misreading of precedent (as with DPP v. Shaban Donasian) by a trial court can vitiate its reasoning even where the ultimate statutory framework is correctly identified, and it delineates the limited applicability of Order XIV rule 5 CPC to judicial review 'applications' as opposed to ordinary suits.
